Has anyone else had an issue with there AC ? ours out of no where began making noises internally so we had it replaced. The new one after 2 weeks the new one blew hot air. Now mind you we did have everything changed so the second failure was not caused by contaminants from the first. So once again they replaced everything again,it not very impressively works. What I find most strange is now we have lost 2 to 3 mpg! Wondering if anyone else has had similar experience.
